Vincenzo' Catini, New-f York, N. Y., 'assignor to Kamket Corporation, New York, N. Y., a corporation of NewYork f Application August 4, 1937, Serial No.'1 57,291 V 3 Claims. (01. 140-93) This invention relates to a device for uniting binder elements and looseleaf s'heets, whichbinder elements may conveniently be made with ma-. chines of the type described inv an application, filed simultaneously herewith. The purpose of the device is to assemble the binder elements and the loose leaves while the rings of the binder elements are open, by inserting the leaves over the free ends of the rings of the binder elements and then compressing the rings to substantially circular formation from their normal oval-formation and thereby close the rings and permanently bind the loose sheets together.

In the drawings, Fig. 1 is a front elevation of the machine; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a detailed section on the line 3--3 of Fig. 1, showing the wire loop in position and the dies open ready to compress the loop; Fig. 4 is a view similar to Fig. 3, showing the dies closed and the formation of a loop completed; Fig. 5 is a front elevation partly in section. on the line 5-5 of Fig. 4; Fig. 6 is a detailed plan view of the lower forming die and Fig. '7 illustrates an assembled binder element and loose leaves permanently bound together.

The machine is preferably permanently mounted upon a table I by the bolts 2 passing through the top of the table and through the bed plate 3 of the device. The bed plate 3 is in the form of an elongated metal block provided in its top face 4 with a slot 5, into which is inserted an elongated die block 6, which is provided with a continuous groove I, having laterally extending grooves 8 extending from the base of the groove 1 through the top surface of the die 6. A branch 9 of the lateral groove 8 extends on the opposite side of the groove I. The contour of the bottom of the groove 1 is flat while the contour of the bottom of the grooves 8 is arcuate in form to accommodate the configuration of the portion III of the ring II immediately next to the tie rods I2. A series of like grooves 8 and 9 are located along the length of the groove 1 corresponding to the distance apart of the rings II of the binder elements. The binder elements, as they are manufactured, consist of ring members made of two closely related sections of wire, shown in Fig. 5, the ring members being generally oval in configuration, as shown in Fig. 3, the free end I3 of the rings being spaced from the tie rods l2.

A binder element thus constructed is set into the groove system 1 and 8 of the die 6 with the tie rods I2 engaging the flat base of the groove I and the portion ID of the ring member engaging the arcuate base of the groove 8. Prior to the insertion of the binder elements into the groove system I and 8, the loose leaves are threaded into association with the rings. This may be done by hand, the ring members being passed through the corresponding perforations in the leaves. As the binder'elements are-placed in the groove system I and 8, the leaves are laid flat'upon the block 6, the bed plate 3 and a portion of the shelf I 4, thereby supporting the leaves wholly independently of the .binderelement and leaving the binder element free for manipulation during the closing operation. A closing die I5 is mounted upon the support I6, which support is mounted to reciprocate upwardly and downwardly and carried by the arms I! and guided by the studs l8. Reciprocation of the support I6 and the die I5 may be manually effected by the foot pedal I9, connecting rod 20, arm 2|, pivotally supported, from the bracket 23. The arm 2| is guided in the U- shaped frame 24 and the length of the stroke of the foot pedal I9 may be adjusted by the adjusting screw 25. The shaft 22 extends lengthwise of the machine and at the ends thereof, beyond the brackets 23, is provided with an arm 26 engaging a link 21 pivotally mounted at 28 on the socket 29 secured to the arms I! by screw-threaded engagement therewith. The closing die I5 consists of a series of aligned formers 30 provided with a depending tongue 3| and two angular faces 32 and 33 arranged substantially at right angles. When the closing die I5 is depressed, the tongue 3| enters the groove I and engages the tie rods, pressing the same against the base of the groove 1. At the same time, the angular faces 32 and 33 engage the oval-shaped rings and exert pressure thereon, primarily in a downward direction, and also in a lateral direction, whereby the rings II are forced downwardly in the groove I, the extension 9 of the groove being provided to permit the free end of the rings II to clear the wall of the die 6 and to guide the free end of the ring in its downward movement. The stroke of the closing die I5 is sufficient to actually force the free end l3 of the ring II beyond the plane in which the tie rods lie, in the base of the groove 7, so that while pressure is exerted upon the rings II, the free ends thereof actually overlap the portions of the rings which are a continuation of the tie rods. In order to permit the free end of the ring to be thus depressed, a well 34 is provided in the path of movement of the free end I3 of the ring II in order to accommodate it in its descent.

When manual pressure is exerted upon the die I 5 in order to force it downwardly, all of the rings are simultaneously closed, as above explained,

and when pressure is released from the foot pedal, the springs return the closing die I5 to its upward position and. as the tongues 3| move upwardly, with the receding closing die, and the pressure is relieved on the rings H, the free end [3 of the ring, by reason of the resiliency of the spring metal, of which the binder elements are formed, springs upwardly and the very tips of the free ends I3 of the rings position themselves closely to the line of junction of the base of the rin with the adjoining tie rod, this relation being so close that the space is insufficient to permit the escape of the individual bound sheets.

The device is of such character that binders of difierent sizes with respect to ring diameters and spacing of the rings may be accommodated. For this purpose, the die 6, which by reason of its own weight is normally retained in the bed plate 3, may be lifted out and replaced by another die and the closing die l5, which is held by the screws 36, may be readily removed and a different form of closing die substituted.

I claim:

1. In a device for uniting the pages of a book with a binder element, a die, a groove lengthwise therein, a plurality of grooves arranged crosswise of said lengthwise groove, said crosswise grooves having an inclined face running from said crosswise grooves to the upper surface of the die, said grooves being adapted to support a binder element comprising a series of open ring-like members joined together by intervening tie rods, a support for the book pages, a pressure member mounted for movement with respect to said die, means upon said reciprocating member adapted to engage the open ring-like members and bend them to substantially complete ring formation.

2. In a device of the character claimed in claim 1, in which the means for exerting pressure on the ring-like members is provided with a horizontal and a vertical surface, in which the horizontal surface exerts pressure upon the ring and the vertical surface guides the ring during closure thereof.

3. In a device for uniting the pages of a book with a binder element, a die, a groove lengthwise therein, a plurality of grooves arranged crosswise of said lengthwise groove, said crosswise grooves having an inclined face running from said crosswise grooves to the upper surface of the die, said grooves being adapted to support a binder element comprising a series of open ring-like members joined together by intervening tie rods, a support for the book pages, a pressure member mounted for movement with respect to said die, means upon said reciprocating member adapted to engage the open ring-like members and bend them to substantially complete ring formation, a projection extending from said die adapted to enter the longitudinal groove and press against a portion of the binder element.
